Why is this manhwa so depressing?

I might be alone on this one but I kinda wish suae ends up alone and actually starts her healing journey. By herself. 10 years with no closure and all she thought about was a man. her life basically stopped the moment eunhyuk left her. making either dude the reason for her new found happiness is just depressing and so backwards. she was a headstrong independent lovely girl in season 1. but now?
this entire triangle constelation is hurting all 3 of them but none of them have the courage to properly move on from these difficult emotions and memories they share. all three of them threw themselves into work and are mentally stuck in highschool. and the guys? they are obviously not doing okay emotionally as well and it’s like all three of them secretely think that a relationship will fix this messed up triangle because them being together back then in highschool was the last time they were genuinly happy. that‘s why all 3 of them keep on replaying memories. literally the worst mental state to potentiall rekindle a relationship. for a relationship to work with someone you have so much history with, you need to let go of the past and be mentally and emotionally stable enough to handle it. but as things are going, I can‘t see either relationship as anything else but an intense traumabond no matter who eventually ends up being end game. there is absolutely nothing romantic about this entire story. how the f did we get here? ಠ_ಠ
